What is PDA (Pentadeca Arginate)?
Plain language first. The technical label stays, but it never stands alone.Overview
It aims to do the same repair job, healing gut, tendon, and muscle, while lasting longer in the body. It is very new.
PDA (pentadeca arginate) is a more stable, arginate-salt cousin of BPC-157.
What it's used for
A newer, more stable cousin of BPC-157, used for the same thing: faster healing of gut, tendons, muscle, and inflammation. It is marketed as longer-lasting.
How does PDA (Pentadeca Arginate) work?
What it does in the body, and where.PDA is BPC-157 as an arginate salt rather than an acetate salt. The peptide chain is the same; the counter-ion is different.
- 01The repair mechanism is BPC-157'sBlood vessel growth and repair signaling, with the same animal evidence behind it.
- 02The arginate form is claimed to be more stableBetter shelf life and survival in the body. This is a formulation claim from vendors, not something established in published work.
- 03It is very new and essentially unstudiedEven by the standards of this category, there is almost nothing published on PDA specifically as distinct from BPC-157.

What else is it used for?
Each use below carries its own evidence level. Approved means regulators have cleared it for that purpose. Investigational means it is in trials. Early research means it is being studied and is not established.

At a glance
Four things to know about PDA (Pentadeca Arginate)
How much, and do you cycle it?
The range, and whether you take breaks.0.25 up to 0.5 mg per day (start low, increase slowly), 1-2x daily. Commonly run in 4 to 8 week blocks, like BPC-157 Community practice
Same convention as BPC-157, which it is a salt form of. No human study has tested a duration.
Nothing publishedNo figure
Nothing published for pentadeca arginate. BPC-157, the sequence it is built on, has no published human figure either.
You can compare this against the whole library to see where it sits.
How do I dose and price it?
Enter your vial and your dose. Pick a mix. We show the draw and the cost.The vial holds a fixed amount of drug. Adding more water does not make more drug, it just spreads it thinner, so you draw a bigger number on the syringe for the same dose.
Choose your mix
Measuring the water1 mL = one full 100-unit syringe.
PDA (Pentadeca Arginate) starts at $34.30 across 9 vendors, typically $3.43 – $4.40 per mg.
10 listings, last read Oct 24, 2026. Shipping and card fees are not included.
How do you store it?
Before mixing, and after.Dry powder in the freezer or fridge. Once mixed, fridge, and use within about a month.
Unmixed lyophilized PDA (Pentadeca Arginate) keeps for a long time cold. Once you add water the clock starts: most reconstituted vials hold up for roughly 28 to 30 days at fridge temperature. Keep it out of light, and do not freeze it after mixing.
What are the side effects and cautions?
Known cautions and warnings for this compound.Solubility, computed: 40% charged residues, 53% hydrophobic. Water usually sufficient.
A first-pass rule from peptide manufacturers' guidance. It does not account for disulfide bridges, salt form or how the powder was dried, and it predicts what should be easy rather than what will happen in your vial.
Who should avoid it
- No published human trials exist, so no contraindications are established
- Pregnancy
- Active cancer, as a precaution given the healing mechanism
Stop and get help
- Signs of an allergic reaction
- Anything unusual, given the absence of human data
Common effects
- Unknown in humans. Despite heavy marketing, there is no published human trial data
